Gwen bought some fruits. She spent $19 more than
56 of her money on some passion fruits. She then spent $9 more than 20% of the remaining money on some guavas. Given that she had $15 left,
- How much did Gwen have at first?
- How many kilograms of guavas did she buy if they cost $5 per kg?
(a)
100% - 20% = 80%
80% of remaining money
= 15 + 9
= 24
1% of remaining money
= 24 ÷ 80
= 0.3
100% of remaining money
= 100 x 0.3
= 30
16 of total money
= 30 + 19
= $49
66 of total money
= 6 x 49
= $294
Amount that Gwen had at first = $294
(b)
20% of the remaining money
= 30 x 20%
= 30 x
20100 = $6
Amount spent on guavas
= 9 + 6
= $15
Weight of guavas bought
= 15 ÷ 5
= 3 kg
Answer(s): (a) $294; (b) 9 kg
